Romney blasts Obama on foreign policy

9/9/12 11:08 AM EDT

President Barack Obama criticized Mitt Romney for having a “Cold War time warp” view of foreign policy in his speech at the Democratic National Convention.

On Sunday, Romney fought back.

The Republican presidential nominee called the Obama administration’s policies toward Iran “perhaps the biggest failure” in foreign policy in the last four years.

“The president has not drawn us further away from a nuclear Iran,” Romney said in an interview on NBC's “Meet the Press.” “In fact, Iran is closer to having a weapon, closer to having nuclear capability than when he took office.”

Romney said his administration would keep “every option that is available to us” open in order to prevent Iran from developing nuclear weapons.

“We need to use every resource we have to dissuade them from their nuclear path,” Romney said. “But that doesn't mean that we would take off the table our military option. That's something which certainly every American would hope we would never have to use. But we have to maintain it on the table or Iran will, undoubtedly, continue their treacherous course.”
